Embodiment 1

[0011] Such as Figure 1-4 Shown is a rain and sewage anti-backflow inspection well, which includes cast-in-place reinforced concrete rainwater and sewage inspection well 1, reinforced concrete cover plate 2, C30 concrete well ring 3, φ700 or φ800 cast iron well cover and support 4, φ700 or φ800 prefabricated concrete well shaft 5, launder 6, step 7, C10 concrete cushion 8, base old soil 9, flap door 10, rubber sealing ring 11, expansion bolt 12, pipe 13; technicians can determine whether to use rainwater or The structural form of sewage anti-backflow inspection well 1, the difference for rainwater or sewage anti-backflow inspection well 1 is the form of flow groove 6 at the bottom of the inspection well. The center of the pipe is flat. When connecting pipes with different diameters, the top of the chute is generally flat with the center of the small pipe. The height of the chute of the sewage inspection well is that the top of the chute is generally flat with the top of the p...

Abstract

The invention relates to the technical field of building water supply and drainage systems, in particular to an inspection well facility capable of preventing rainwater and sewage from flowing backwards. The inspection well is mainly characterized in that the drainage of rainwater and sewage in industrial and civil building parks is conducted in a one-way mode and is reversely cut off, namely, the drainage in the industrial and civil building parks such as residences, business, offices, commercial complexes and plants is conducted in a one-way mode under the gravity flow or natural state of the rainwater and sewage in the parks, and the municipal rainwater and sewage are prevented from flowing backwards to the parks. According to the invention, the problem of serious water accumulation or waterlogging of the industrial and civil building parks such as the residences,the business, the offices, the commercial complexes and the plants due to backward flowing of the municipal rainwater and sewage into the parks due to too shallow burying of municipal rainwater and sewage pipelines or too large municipal rainwater and sewage quantity in the urban construction process is fundamentally solved.

Description

technical field [0001] The invention relates to the technical field of building water supply and drainage systems, in particular to a rain and sewage anti-backflow inspection well facility. Background technique [0002] With the development of the social economy, the industrial and civil construction industries have also developed vigorously. Therefore, the smooth discharge of rainwater and sewage inside the industrial and civil construction parks has played a vital role in the quality and comfort of the park. Due to recent years Climate uncertainty and the hysteresis and backwardness of the supporting construction of the municipal pipe network, the stability and reliability of the drainage of the construction park are increasingly demanding. Contents of the invention [0003] The purpose of the present invention is to overcome the problems existing in the prior art, and provide a facility based on the anti-backflow inspection well, which can fundamentally solve the proble...
